I use stock charts.com.Note that 10/20/2021 is the first date reported by Yahoo and Barchart.com.
BITO (ETF) from 10/20/2021 to 6/22/2023: return of -56.98% (including dividends)
BTC (underlying) from 10/20/2021 to 6/22/2023: return of -54.39%
HODL outperformed U.S. ETF.
They show 1st trading day as 19th of Oct. What a difference a day makes.

But you are right BTC does seem to be just ahead of BITO. (My bad)
Both seem to be down over 50% in the time frame you referenced.
Only have to gain over 100% to be at breakeven.
